Problems solved by technology

One of the biggest safety concerns with towing trailers is that the trailers may sway, leading to loss of control of the towing vehicle.
Some trailer hitches may not handle these situations well and may often exacerbate the sway problem making driving even more stressful and difficult.
Another common problem encountered when towing a trailer is “highway hop,” or the bouncing that often happens to trailers on uneven roadways.
This problem may be caused by uneven weight distribution.
The uneven distribution of weight may make steering control more difficult, especially during emergency situations.
Risks associated with driving a trailer without a weight distribution hitch may include loss of steering control, braking difficulties, and hitch dragging.
A single fixation point allows for off axis loads to cause rotation 77 about the point, which greatly increases wear.
A drawback of the prior art brackets formed as rigid members is that the fastening member 56 may wear and enlarge the openings 51 such that the bracket 28 does not provide stabilizing support to the spring bars 26 relative to the tongue 16.

Abstract

A trailer hitch system for equalizing trailer loads and reducing trailer sway. The trailer hitch system may include spring bars that may be attached to a hitch head using a trunnion style connection. The spring bars may be attached to the trailer using rigid brackets that reduce swinging of the spring bars. The rigid brackets having a plurality of contact points may include an upward extending portion for attaching to the trailer tongue, and a lateral extending portion for receiving the spring bars thereupon. The rigid brackets may include a spacing member and an attachment member.
